Vegetable Production using Subsurface
Drip Irrigation. Onion and Watermelons will be irrigated
with SDI to evaluate the yield response to different irrigation
water levels (2nd year). The experiment will be
conducted at the Weslaco Experimental Station. I am the
principal investigator. Other investigator is Dr.
Jifon. The experiment consists of four treatments and four
replications. Jose Morales will be helping with the
demonstration.

Grain production under water limiting
conditions. Corn and sorghum will be grown under
different irrigation levels to obtain optimum irrigation levels.
Other investigators are Drs. Jifon and Nelson. Jose Morales
will be helping with the demonstration.

Impacts of Best Management Practices on Nutrient
Loadings to the Arroyo Colorado. Several farms will
be monitored to assess the effect of different BMPs on irrigation
efficiency and nutrient loadings. A relation will be
determined between irrigation management, water use and
environmental pollution. The data will be used with SWAT model to
simulate different management strategies. A post doctorate will be
hired to help with the SWAT modeling. Xavier Peries will be
collecting the data from the sites.

TWRI and the Texas A&M Natural Resources Institute are working together to foster and communicate research and educational outreach programs focused on water and natural resources science and management issues in Texas and beyond.
